Juan Manuel Marquez comes in at 133.5 pounds for title fight

All main card fighters make weight for Golden Boy’s weekend event

WBA/WBO lightweight champion Juan Manuel Marquez of Mexico City poses on the scale during an official weigh-in at the Mandalay Bay Events Center Friday, July 30, 2010. Marquez takes on Juan Diaz of Houston, Texas for a rematch at the events center on Saturday.

Lightweight world champion Juan Manuel Marquez tipped the scales at 133.5 pounds during Friday's official weigh-in for his title fight against Juan Diaz this weekend at the Mandalay Bay Events Center.

If all goes well for Marquez, it might be the last time he weighs in that low the rest of his career.

A potential meeting with current junior welterweight champion Amir Khan awaits Marquez if he's able to defeat Diaz, who came in at 135 pounds.

While some fans are looking ahead to that potential matchup, Marquez says his focus is solely on what lies directly ahead of him.

"Right now, my mind is set on 135 pounds," said Marquez earlier in the week. "After the fight, we'll sit down and see what's next."

Marquez (50-5-1, 37 KO) defeated Diaz (35-3, 17 KO) via TKO in the ninth-round in their previous meeting Feb. 28, 2009. The fight was voted 2009 Fight of the Year by the Boxing Writers Association of America.

Golden Boy Promotions brought its biggest starts to Friday's weigh-in, including Khan, WBA heavyweight champion David Haye and former world champion Bernard Hopkins.

Professional basketball player Caron Butler also was in attendance and predicted a win for Marquez.

Saturday's card also features a middleweight world title fight between Daniel Jacobs (20-0, 17 KO) and Dmitry Pirog (16-0, 13 KO).

Doors open at the Mandalay Bay Events Center at 1:45 p.m. Saturday. The event also is available on HBO pay-per-view.

Demetrious "Mighty Mouse" Johnson slammed his hands down on his UFC flyweight championship belt. Somewhere else in Rogers Arena, Rory MacDonald surely looked on with envy. Johnson and MacDonald put on dominant performances in the UFC's first trip to Vancouver in three years. Johnson defended his title for the fourth time, not allowing Ali Bagautinov to win any of their five fast-paced rounds. That couldn't quite top MacDonald, who barely let Tyron Woodley touch him in an all-important welterweight co-main event. MacDonald hopes the performance leads him to an opportunity to claim space alongside Johnson in the UFC champion's club.
